Sierra Club Florida is elevating Cris Costello to State Campaign Director.
Costello has been on Sierra Club’s roster since 2007 and most recently served as the Florida Chapter’s Senior Organizing Manager, where she helped guide and grow many of the Chapter’s core campaigns.
In her new role, Costello will expand upon her prior leadership of the Our Wild Florida campaign — a comprehensive statewide effort focused on Everglades restoration, combating red tide, fighting sugarcane burning, and protecting Florida’s wildlands.
Before joining Sierra Club, she worked as a grassroots organizer in multiple states, served as a Peace Corps volunteer in Honduras, and spent 17 years as a union organizer and contract negotiator. She holds a Bachelor of Arts degree from Grinnell College in Iowa.
“For nearly 20 years, Cris has been a driving force behind some of Sierra Club’s most impactful organizing work. Her strategic leadership, key partnerships across the state, and unwavering commitment to protecting Florida’s environment make her an asset to our Chapter’s mission, and we are proud to elevate her to the role of State Campaign Director,” said Sierra Club Florida Chapter Director Susannah Randolph.
Costello said she was “deeply honored” to step into the role.
“Florida is on the frontlines of the climate crisis and environmental injustice, and our work at Sierra Club has never been more important than it is today. I look forward to deepening our Chapter’s campaign work and helping to deliver bold, meaningful action to meet this critical moment,” she said.
